MORGAN MORGAN, OF ANAGONDA, MONTANA.

Application filed April 17, 1922.

To all iff/0m t may con Be it known that l, MORGAN T. MORGAN, a citiz/:en of the United States, residing at Anaconda, .in the county of Deerlodge and State of Montana, have invented certain new and useful improvements in an lncubator, o1 which the following is a specilication.

'.ihis invention is an incubator' and has for its principal object the production of a device which will facilitate the removal of the egg trays from the interior of the incubator without necessitating the opening of a door which would allow the heat to escape jfrom the interior of the incubator.

.,lrxiother object of this invention is the jxnoduction of an incubator wherein a tray supporting frame is provided, this supporting 'frame being removable, whereby the lower portion of the main housing, or heat chamber, is open, thus allowing the tray to be movably supported, whereby when so desired, the tray may be lowered to allow access thereto, without necessitating` the opening of a door at the upperportion of the main housing, thus preventing unnecessary escape of the heat from the housing.

Another object of this invention is the production ot an incubator wherein the tray supporting trame is provided with a lift ing mechanism, thus permitting the tray to be carried within the main housing, at which time, it will constitute a closure for the lower portions of the housing, or when desired, the tray may be lowered to permit access thereto.

Another object of this invention is the production of an incubator including a movable tray supporting trame, this trame being so constructed as to carry trays in convenient position to allow access to the trays when the frame is lowered, thus preventing the escape of the heat in the upper portions oi the main housing.

One practical form of construction and assembly of the present invention will be hereinafter described and is illustrated in the accompanying drawing, in which- Figure 1 is a top plan view of the incubator,

Figure 2 is a front elevation of the device, and

Figure 3 is an elevation of the tray carrying frame.

In the preferred embodiment of the present invention, about to be described, it will NCU'BATOR.

be seen that the' main housing comprises a top 5 having side walls r6. The corner standards Z are connected to the side walls 6 although the standards project for aconsiderable distance below the lower portions of the walls and constitute a support for the main frame.

It will be noted, by referring to Figure 2 that the lower portion of the main housing is open and thus allows the tray carrying frame to be. hereinafter described to be .moved into or out of the housing, as desired.

One of the walls 6 is provided with a sight opening 8 having a glass panel 9, thus permitting a view of the interior of the main housing when desired. It will further be noted that the wall is also provided with an enlarged opening 10, whereby egg trays may be removed from or inserted within the housing which constitutes the heat chamber, as shown in Figure 2. It is of course obvious that any form of a door or closure, not being deemed necessary to be herein illustrated may be employed for closing the opening 10.

The traycarrying frame comprises a pair of parallel supporting beams 11,upon which are carried the boards 12, as shown in Figures 2 and 3, wherein a closure is provided for the bottom of the housing, when the trame is carried therein. The supporting` walls 13 are carried by the beams 11 and these walls extend parallel to cach other. The reinforcing cleat 14k may be secured to the supporting` walls 13, as shown in Figure 3, thus holding the walls from spreading or collapsing and Jor this reason causing the walls to be retained in their correct posi tions at all times. It will further be noted that the supporting strips 15 are carried upon the inner surfaces of the supporting walls 13, the strips of one wall being in horizontal alignment with the strips of the ref maining wall. Accordingly, an egg tray 16 be placed upon each pair of strips, as shown in Figs. 2 and 3, and thus be removably supported upon the tray carrying frame.

The I bolts 17 are carried at the ends of the beams 11 and are retained in adjusted position by the nuts 18. The drum 19 has caps 2O carried upon its ends which are held against displacement by the pins 21. rlihe stub aXles 22 extend Jfrom the caps 20 and project through the bearings 23, fixed as indicated at 24 upon the top 5 of the main housing. Therefore, it will `,be seen that the drinn 19 is rotatably supported. 1t will be noted that the crank 25 is connected to one of the stub axles Q2, as illustrated in Figures 1 and 2, and tor this reason when the crank is swung it will also rotate the drum 19. ln order to hold the drum against rotation in one direction, there is provided a ratchet wheel 2G secured adjacent one ot the. caps v2O and this ratchet wheel is engaged by the pawl 2T mounted upon the ears carried by one of the bearings 2, as shown at 28.

Guide pulleys 29 are carried by the castings 30 adjacent the side edges of the top ot the housing, it being noted that the pulleys are carried in alignment with each other, as illustrated in Figures 1 and 2. Cables 31 pass through the drum 19 or may be secured thereto in any desired manner and also pass around the guide pulleys 29. rlhc ends oit these cables 3i are connected tothe I bolts 17, as shown in Figure Q.

Then this invention is in use, the drums may be rotated in one direction atter the pawl 27 has been released from engagement with the ratchet wheel 2G. Therefore, the cableslli will lower the egg tray carrying trame. Before such action takes place, it v*is obvious the interior ot the main housing may be viewed through the sight opening andthen the trarne may be lowered to allow oi access to the desired tray 16 carried upon the. tray carrying frame. As access to the tray may be had through the opening 10, it is obvious the trays may be removed and Vanother tray inserted in lieu thereof, or the eggs carried by thetray may be partly removed, or in 'tact any other operation desired may be performed. It is obvious the frame may be lowered as tar as desired by the release ot the cables by the drinn 19.

During this movement, it is obvious that the movement of the trame downwardly from the lower portionsot the main housing, will obviatc the i'iecessity ot a door in the top ot the main housing which would allow `he heat in the main housing to escape. rlheretore,the housing may have a comparatively `even temperature, tor the necessary operation in connection with the turning ot the in connection with ordinary incu- Jators will take k place yat the lower portion ot the device andthusfthe heat within the upper portions ot the housing will be retained.

fitter the desired operation has taken place, the drum may be rotated in the opposite direction and the cables 31 are wound upon the drum and pass upwardly over the guide pulleys 29 and thus lift the beains 11.

Therefore, as the beams 1l are lifted it is obvious the tray carrying' trame may be moved into the interior of t-he housing, or into the heat chamber thereof, as hereinbetore explained. The boards 12 will constitute a solid closure for the bottom of the main housing, aitei thel frame has been returned thereinto and for this reason heat is positively prevented Yfrom escaping to any great degree by the closing ot the lower portion ot the housing.

lt is obvious that any toi-m ot a closure may be employed for the opening 10, as hereiiibet'ore explained whereby the incubator will opera e in the usual manner.

From the foregoing description, it will be seen that an incubator has been provided wherein the egg carrying' trame removably mounted, thus permitting the same to be lowered from the bottoni of the main housing when access is desired to the tray.

Accordingly, an unlimited escape of the heat carried within the housing is prevented while the cables connected tothe 'trame will be easily actuated igor thefmoving ot the tray either into or out of the housing by the rotation ot' the drum 19.

The foregoing description and the drawings have retercnce to what may be considered the preferred, or approved, form oi my invention. lt is understood that I may make such changes in construction and arrangement and combination o't' parts, materials, dimensions, et cetera, as may prove expedient and tall within the scope of the appended claim.

Having thus Ylully described my invention, what claim as new and desire to secure by Letters Patent, is:-

in incubator comprising a main housing including a top wall, side walls, and a vertical movable bottom wall, supporting legs tor the main housing extending below the lower surface thereoit and torn'iing a guide lor the lower wall, au upstanding frime carried by the lower wall adapted to extend into the main housing7 a sliding egg supporting tray associated with the traine, the lower wall being extended beyond the side walls the housing and the legs and provided with supporting eyes, a ,transversely attending rotatable drinnv carried by the top wall and disposed at a point equi-distant from the ends thereof, means tor rotating the drum, the guide pulleys carried by the top wall and arraiiiged on each side of the drum, and lifting cables secured to the extended portions of the lower wall and trained about said pulleys and secured'to the drum, as and for the purposespecified.

ln testimony whereof I allix my signature.
